bugfix constrain and point deletion: By moving the brush back and deleting previous points, a crash could have happened when shift-constrain is active and the very first point is hit.

bugfix face extrusion: Face extrusion may have been broken under certain situations.

bugfix selection display: In some versions of max the display during selection painting, or a "redo" of such operation might not have been visible, despite actually affecting the mesh, and becoming visible if another selection operation is performed.

bugfix redraw problem: higher max versions only showed changes by other commands (for example key binding for NURMS toggle) when the viewport is changed afterwards. This problem stayed around despite AIF disabled. The root cause lies within changes of 3dsmax itself in regards to maxscript value handling and is therefore unknown, a workaround was put in place. (Thanks to Warren for reporting)
